Specification of Letters Patent.

Patented Apr. 28, 1914i.

Application filed January 17, 1914. Serial No. 812,660.

To all whom it may concern:

Be it known that 1, Hnnronn C. JUDsoN, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Milkingu Machines, of which the following is a speciiication.

My invention relates to a mechanical milking device which is simple in construction, positive in action, and in which the parts are readily adjustable1 so as to accommodate varying conditions encountered in service. My device is adapted to act by the pressure of a resilient steel ribbon or spring, one end of which is fixed, the movement of the other end being limited to :1 rectilinear path, motion being imparted te the spring or ribbon by means of a crank and Pitman. .lhrough this means acting against a fixed opposed surface, a downwardly progressive compression is obtained which simulates the operation of hand milking and closely approximates the action of a calfs tongue and mouth in feeding,

In the accompanying drawings which form a part of this specification, Figure 1 is a plan view of my improved device; F ig. 2 is a perspective view of the frame in wnich the parts are assembled; Fig. 3 is a perspective view of one of the individual box frames in which the milking mechanism is contained; Fig. e is a transverse sectional view on line lV--IV of Fig. 1; Fig. 5 is a transverse sectional view on line V-V of Fig, 1; Fig, (3 is a similar View showing the parts in a different stage in the cycle of operations. Figs. and 8 illustrate an alternative construction of the connection between the compression member of a milking unit and the crank.

Referring to the drawings in detail, the numeral 1 designates the rear member of a frame provided with side members 2 and 3 and a removable end member d which may be attached to the ends of the side members by means of screws 5. Journaled in the end members is a crank shaft 6 which terminates at one end in a crank 7 or other means for causing the rotation of said shaft. lWithin the main frame are four box frames 8 identical in construction but arranged in two oppositely disposed pairs. At one side of each frame is a vertical post 9 which carries the sleeve l0 held in place by the set screw 11. Each sleeve has projecting therefrom a threaded stud 12 adapted to pass through one of the slots 13 in the side members of the main frame. The nuts 111 and 15 mounted on each stud provide for rigidly clamping the box frame S to the main frame. This arrangement provides for adjustment of the box frame within the main frame in the direction of the slots 13, in adirection perpendicular to the side members of the main frame, and along the vertical posts. In the upper portion of each of the box frames is a pair of oppositely disposed slots or guides 16 in which are received the ends of the bar 17 carrying the free end of a flat flexible ribbon or spring-like member 18, the lower end of which is secured to a bar 19 carried by a bracket Q0, which is provided with an externally threaded stud 2l passing through the vertical slot 22 in the box frame. Nuts 23 and 241 provide for the adjustment of this bracket both vertically in line with the slot and also in a direction perpendicular thereto along the axis of the stud. To the central port-ion of the flexible member 18 are secured a pair of bearing members 25 in which is journaled a transverse pin 26. To this pin is secured one end of a connecting rod comprising the end portions 27 and 28 connected by a turn bolt- 29, by means of which the portions 27 and 28 may be brought nearer together or forced farther apart in order to provide for adjustment, The end member 28 of the connecting rod is rotatably mounted upon one of the offset portions 30 of the crank G. A. back member 31 having a curved face 32 opposite the flexible member 18 is secured to the side of the box frame facing that member by means of pins 38 and Se and the studs 35 entering the slots 16.

`When the shaft G is rotated, it will cause the connecting rods journaled on the crank portions to reciprocate, thereby causing the flexible member to function. 1t will be observed that the movement of this member is limited, its base or lower edge being affixed to the stationary bar 19, while the upper end connected to the bar 17 is free to reciprocate only in the plane of the grooves 16. Some alteration in the configuration of the member is possible owing to its resiliency, but it will always be controlled by the limitations imposed upon the movement of the free end and the fact that the other end is fixed. Y

The approximate cycle of operations is for imparting a reciprocat-ing motion to an intermediate portion of said movable member.

6. In a milking machine, a movable teatengaging member comprising a thin fiexible metallic ribbon, and means for imparting a reciprocating undulatory motion to said ribbon.

7. In a milking machine, a movable teatengaging member comprising a thin flexible metallic ribbon having one end fixed, and means for imparting a reciprocating undulatory motion to the free portion of said member.

8. In a milking machine, a movable teatengaging member comprising a thin leXi ble metallic ribbon, one end of which is iixed, means for limiting the motion of the other end to a predetermined path, and means for imparting a reciprocating motion to an intermediate portion of said member.

9. ln a milking machine, a movable teatengaging member comprising a thin flexible metallic ribbon, one end of which is fixed, means for limiting the motion of the other end to a rectilinear path, and means for impart-ing a reciprocating motion to an intermediate portion of said member.

10. In a milking machine, a iiXed member, a movable teat-engaging member comprising a thin tlexible metallic ribbon having one end liXed, means for limiting the motion ot the other end of said ribbon to a direction substantially perpendicular to the adjacent surface of said fixed member, and means for imparting a reciprocating motion to an intermediate portion of said ribbon.

11. In a milking machine, a movable teatenf/aging member comprising a flexible element and means for imparting to the central portion of said element an undulatory motion having a reversal of curvat-ure at each cycle.

12. In a milking machine, a movable teatf engaging member comprising a thin eXible ribbon having one end fixed, means for limiting another portion to a predetermined path, means for imparting a reciprocating motion to a portion of said ribbon, and means for altering the initial position of the iiXed portion of said member.

13. In a milking machine, a rectangular frame, a plurality of individual milking units arranged in oppositely disposed pairs and adjustably mounted upon said trame, and an actuating shaft centrally disposed with reference to said units and carried by said frame.

14. In a milking machine, a rectangular frame, a plurality of individual milking units arranged in oppositely disposed pairs and adjustably mounted upon said trame, a crank shaft centrally mounted With respect to said individual units and journaled in said frame, and a connecting rod leading from said crank shaft to each of said individual units for actuating the same.

15. In a milking machine, a rectangular frame, a plurality of individual milking units arranged in oppositely disposed pairs and adjustably mounted upon said frame, a crank shaft centrally mounted With respect to said individual units and journaled in said frame, and a connecting rod of adjustable length leading from said crank shaft to each of said individual units for actuating the same.
